Notes:
1. Pins V and R are routed from a terminal strip on the rear of the Step Pak chassis. This power is separate from the power delivered to the encoder connector pins 4 and 9.
2. If this connector is to be used with a 4-lead motor, the second set of leads (winding 2) should be connected to pins 'C' and 'H'.
